------------------------------------------
Hi Oliver,
Thanks for contributing the patch.
It works perfectly, except for non-numeric queries. I fixed the problem by
merging your patch with LUCENE-3338 (a patch with the new changes is attached
there as well).
I will take a look at your patch for 3x later.
